2. Levels of cell organization

3. Cells are the basic building block of all living things.
All living things are composed of cells.
All cells come from pre-existing cells.

4. Blood Cells
Nerve Cells
Asparagus cells
Variety of Cells
Human Muscle Cells
Bladder Cells
Onion Cells
Epithelial Cells

5. Similar cells are organized into tissues.

6. A tissue is a group of cells that are similar in shape and function.
Nerve Tissue
A tissue is a group of cells that are similar in shape and function.
Bone Tissue
Areolar tissue: Connective tissue that surrounds organs and lies under the skin.
Muscle Tissue
Connective Tissue found at the ends of bones.
Elastic Cartilage tissue found in the human ear.
Epithelial Tissue
Connective Tissue

7. Tissues are often organized into larger structures called organs.
Tissue A
Tissue B
Organ
Tissue C
Tissue D
Tissues are often organized into larger structures called organs.

8. Organs
Human Heart
The Brain
Lungs
Human spleen

9. Organ Systems are groups of organs that have related functions.
For example, the circulatory system includes the heart; arteries that carry blood from the heart to the tissues; capillaries where nutrients and wastes are exchanged; and veins that carry blood and wastes from the tissues back to the heart. Nerve tissue, blood, epithelial tissue, connective tissue, and muscle tissue are all found in the circulatory system.
